DH and I just bought in on our trip in July. We were not planning on buying at the time so we hadn't really discussed it much; something I would highly recommend doing before the tour if there is any possibility that you might buy in
The factors we considered:
Price per point
Maintenance fees
Hotel location
Number of points/night
Amenities for little ones (our DD is 9 mos)
Ease of point rental or resale
Initially we were thinking solely about price and ability to rent. We ended up buying in GCV. My husband's office is located in San Diego (he works from home in NY) so we thought it would be great to have a place to stay out there until we realized his trips are booked 1 month in advance, max. So the 11 month advantage of booking there didn't matter.
We ended up buying BLT over AKV. We fell in love with the room at AKV. However, there are a lot more rooms at AKV and so far have had no trouble booking a room there (even value) at 7 mos or less. We know that it's going to be much harder to get a room at BLT at 7 mos, especially if we want MK view.
The monorail is huge for us and the proximity of MK. I was worried that it would be a 15 min walk to the monorail, but our guide assured us that it was less than 10 min to get there, plus it's inside away from the heat! The top of the world (I think that's the name) lounge is a great selling point too. Taking DD up in her pjs to watch then being able to just walk downstairs and go to bed w/in 10 min instead of having to fight crowds and wait in long lines for buses.
If we do need to rent, we also feel that it will be easier to rent out BLT points than AKV. I think our guide said (correct me if I'm wrong!) that there are less than 300 BLT rooms and over 700 AKV.
The rooms feel like you're in a posh NYC hotel. It's very nice. It's not the same feel as AKV, which we did like more and found more relaxing, but we wouldn't regret staying there ever! That would not be the case for us at OKW or SSR. They are beautiful resorts, we almost bought at SSR till we realized how big it was. We stayed at POR in July and I hated it. It was beautiful, but HUGE. I prefer a smaller resort. I'm so glad we did stay there though so we knew that we didn't like that kind of resort layout. We don't ever want to have to rent a car. For us, we love the ME and being able to rely on Disney transportation. Staying at a big resort makes transportation a pitb imho.
The incentives currently were great, which in the end, is why we bought when we did. We got 170 points with a financed amount of $15k. We knew DH was getting a profit check in Sept that would be enough to pay it off and we wouldn't end up having to pay any interest since our payments don't start till Oct.
Also think about how many times per year you'd like to travel if you absolutely want to stay at your home resort. If we wanted to take 3 trips a year at BLT, we couldn't do it on 170 points. We could however do it easily at AKV in a value room. Something else to think about
So let's see, bullet points in case you skipped over my long-winded-ness.
~anticipated ease of renting out points at BLT
~MONORAIL access to MK and restaurants at GF, Poly
~Fireworks lounge viewing area
~Pool (Kidani pool I'm told is awesome for kiddies!)
~room comfort
~where you want 11 month booking window
~size of resort. Hotel vs large condo style
~How many trips per year you want and can get out of your points at your home resort.
Sorry this is so long! Good luck in your research and decision! If you have any more questions, feel free to PM me!
